Definitions

  • sealable cover layers also contain a resin
  • the resins listed above for the base layer can be used.
  • the distribution factor is defined as where C G is the total ethylene content in the copolymer in% by weight and C i is the percentage of ethylene in% by weight which is present as an isolated ethylene component, ie a single ethylene component is isolated between two propylene components in the manner outlined below:
  • the multilayer film according to the invention is distinguished in particular by the improved barrier properties with regard to the passage of water vapor and oxygen, its outstanding optical properties and the described increased shrinkage properties in the longitudinal and transverse directions.
  • Their surface gloss (measuring angle 20 °) is greater than 100, preferably 105 to 130, determined in accordance with DIN 67 530, and the haze of the film (measured in four layers) is less than 22%, preferably 10 to 18%, the haze measured in accordance with ASTM-D 1003-52.
  • the shrinking multilayer film according to the invention has a combination of properties which makes it particularly suitable for its intended use as packaging film or wrapping film on high-speed wrapping machines. It has all the properties that are required by polyolefin films with regard to tight, wrinkle-free and wave-free, brilliant, effective advertising. Due to their improved barrier properties with regard to the passage of water vapor and oxygen, the packaged goods or foodstuffs stay fresh much longer.
  • the scratch sensitivity is determined based on DIN 53 754.
  • Example 1 The superiority of the film according to the invention corresponding to Example 1, Example 2 and Example 3 is clearly shown in Table 1.
  • the comparative examples 1 to 3 show good properties for individual points, but none of these multilayer films according to the comparative examples can meet all the requirements at the same time.
